I am running IOS 12.2(55)SE3 on everything, and all of my 3560's seem
to be fine, problem is with the 3750's. I do get the Ieee PD, show
power inline- I can do a port by port power inline never/auto still
stays stuck there.

We're dealing with a similar issue right now too, but it seems to be
AP-independent. We have a mix of Cisco 3500's and 1250's running on Cisco
3750EPs (running 12.2(53)SE2) and a sample of each type of AP experience the
problem. Our 3750's are Gigabit so I've been using the 'test cable-diagnostic
tdr' feature to see if there might be a cabling issue and in 95% of the cases
it shows that pairs A and B are swapped between the local and remote ends. I'm
still not sure how much I trust those results since they include 3 separate
runs of cable (cross connect, infrastructure, and jumper at the AP) but it's
still something. We figured out a workaround of sorts by hardcoding the ports
to 1000M full duplex and it seems to work in most cases. For the rest, either
reseating or replacing the cross connect has fixed it.
In all cases, the tell-tale indicator is a value of 'IeeePD' in the Device
field of a 'show power inline | ex off'. I've seen that happen whether or not
the line protocol on the port is up, oddly enough. I've got an email out to
Cisco to see if this might be some undocumented bug or...what. If I get
anything worthwhile back I'll share.
Thanks,

Vicki,
If I remember correctly the power module in the cisco switch controls ports
in groups of 4. Try and move one of the dead access points to a port in a
group of 4 that does NOT already have an access point in the group. I've
seen issues like this before but not on a 3560.

Do a "show power inline | i AP", this will filter out the APs on the

Hello, I am running multiple Cisco 4404 controllers Vers-7.0.116 and
the majority of the WAPS are CAPWAP 1131's . The issue I seem to be
having is that lately when I reboot an access layer switch, POE, 3750
series, with WAPS attached, I lose some of the WAPS. The WAPS never
come back on line again and appear to be dead. They were completely
operational prior to the reboot, but after reloading the switch, no
switch configuration changes, the WAPS never come back on line. I
have shut/no shut the interfaces of the switch, and the switches POST
seems fine. Just wondering if anyone else has seen this issue, I
have lose about 30 WAPS so far. Thanks!!
